CCITT 2.048M/NX64K DATA INTERFACE
Information
The 2.048M/Nx64K Data Interface allows the FIREBERD
mainframe to test communications equipment and systems that
comply with CCITT G.703, G.704, G.732, 2048 kbps, and Nx64
kbps signal recommendations for framed or unframed data.
The 2.048M/Nx64K Data Interface allows any selection of Nx64
kbps timeslots within the 2.048 Mbps signal to be accessed
for bit error analysis. This allows real-time analysis of
any number of timeslots (up to 30 o, 31, depending on the
selected multiframing).
1.2 INTERFACE FEATURES __
The 2.048M/Nx64K Data Interface has the following features:
• Unframed or framed 2048 kbps signal analysis with TS-16
CAS (Channel Associated Signalling) and/or CRC4 multiframing.
• Nx64 kbps or Nx56 kbps analysis with unrestricted timeslot
selection.
• Nx64 insert mode.
• Round- trip del ay1 measurement.
• Frequency measurement.
• Timing Slips and Wander1 measurements.
• Jitter2 measurements.
• Positive and negative base-to-peak digital signal level
measurements, in dB.
• In-service monitoring.
• G.821 performance analysis.
• Four selectable transmitter timing sources.
• Programmable timeslot and ABCD IDLE codes.
• Selectable MSB or LSB stuffing in Nx56 kbps analysis mode.
• Selectable voice coding: A-Law or ji-Law.
• Single or consecutive FAS Word error insertion.
• Logic and/or code error insertion (single or variable rate).
• AMI or HDB3 coding.
• Test loopback.
• Voice mode through a telephone handset.
• ABCD signalling access with CAS multiframing.
• Selectable input termination, including MONITOR mode.
• Output line build-out level selection.
• Display Frame Alignment Signal, Not Frame Alignment
Signal, Multiframe Alignment Signal, and Receive Byte of
selected timeslot.
• Transmit alarms.
• Programmable TSO national bits, international bits, and
TS- 16 spare bits.
• Broadcast mode.
• 2Mbps alarm detection.
